mktime

Description

int mktime(int hour, int minute, int second, int month, int day, int year);

Returns the Unix timestamp corresponding to the arguments given. This timestamp is a long integer containing the number of seconds between the Unix Epoch (January 1 1970) and the time specified.

Arguments may be left out in order from right to left; any arguments thus omitted will be set to the current value according to the local date and time.

MkTime is useful for doing date arithmetic and validation, as it will automatically calculate the correct value for out-of-range input. For example, each of the following lines produces the string "Jan-01-1998".

Example 1. mktime() example echo date( "M-d-Y", mktime(0,0,0,12,32,1997) ); echo date( "M-d-Y", mktime(0,0,0,13,1,1997) ); echo date( "M-d-Y", mktime(0,0,0,1,1,1998) );
